24 Xcode Tips in 15 Minutes

[@remyblas]

I'm about 2/3 into the 100 Days of Swift course and this is gold! First, because it will help me navigate and follow the projects quick and easily, and second, because I came here just curious, expecting not to understand most of it, but I do understand almost all of it, and that makes me feel like I really progressed in my understanding of iOS programming.

[@rednettle]

Paul you are a legend, thanks for sharing these, 10 years doing Xcode development and didnt know half of these - My current fave is "Run without building" when you just want to restart the app without re compiling "ctrl+cmd+r"

[@chrispy104k]

Absolutely excellent Paul. My favourites: 1. In storyboard, Hold the Option key and then select the Source code file which makes sure that assistant editor is opened with the right file to make your connections 2. To go back to the file list no matter where the navigator panel is currently - Command + 1 3. Shift + Command + K to clean the build folder. Apparently Shift + Option + Command + K is supposed to perform a deeper clean. No idea if this is fact or fiction. 4. Command + R to run, Command + B to build 5. Mulit-position editing. Select the first location then hold Shift + Control then select the other locations to edit. Massive time saver. That should do for the moment.

[@pieterbikkel]

Great tips, the auto spelling and grammar is my favorite

[@AlanW]

0:28 was just something I was bemoaning about classes yesterday! Thanks!

[@volimpia]

My favorite Xcode shortcut is selecting part of code and choosing refactor extract it to method. Makes code so clearer.

[@GaryLutchansky]

Astoundingly helpful! Thank you, Paul.

[@DogeWowzie]

The spelling check and the extended mini map navigation will be a game changer in my daily developer routine. Thanks for the excellent video. You are an awesome guy.

[@mattlarsen]

Favorite additional tips: CMD-Shift-Y to show/hide the debug area and Option-click on view controller when in the storyboard to display on screen and drag button actions over. Great series!

[@DavidBobSmith]

I don’ t really have a favorite tip that you’ve gave they’re all good one. Thank you!

[@edtrip_]

7:00 Blow my Mind!! Thanks

[@acjazz01]

I loved that tip about generate initializers!

[@JonJudelson]

Multiline Editing in Xcode is one of the most mind blowing features I have ever seen.

[@squarefrog]

So many good tips! I love the Structure > Move Selection Up or Down feature with cmd+opt+[ or cmd+opt+]. Works for both a single line of text, or many! Even more useful when writing SwiftUI

[@adlsfreund]

When was this added?

[@squarefrog]

@@adlsfreund the feature has been there for a long time. The shortcut appeared in 2014 I believe.

[@techguy0711]

I like the triple slash comment that provides a description for a function or class when using autocomplete

[@imamad]

The interface maker shortcut was the best one for me! It's super helpful for code review and refactoring.

[@asigivati1382]

wow impressive tips! i''m using xCode something like 6 years and i learned lot of good stuff here! thanks!

[@mohammadabuqubu7079]

Filtering the jump bar was life savior

[@goalsandapps7847]

You got my thumbs up already after the very first tip.

[@judy8821]

Great tips! Knew some of them. One tip for SwiftUI that I am careful to follow, is to not type too much code before building because the error messages don’t make sense so you can’t pinpoint which line of code is wrong until you start deleting all the lines you entered until you find the one.

[@leifashley]

Probably the best Xcode tips list I've ever seen. I knew like only 2 of these, so the rest were pure gold :)

[@davidagyakwa288]

the best Swift and swift ui tutor there is 🔥

[@govind20246]

Initializer method is awesome 👍, thanks for sharing this!

[@naturereporter2719]

IAP testing in Xcode. Awesome! Ty for this vid.

[@theDaveBaxter]

Dbl click the brace is defo gonna help. Am forever scrolling up and down trying to find matching braces.

[@casperes0912]

Haven't watched alll the vid yet, so don't know If it comes up, but here's the best thing I ever did for myself in Xcode. I bound the Refactor->Rename option to F13. Now I just place the cursor over a variable or function name, F13, write new name, enter. Boom, renamed everywhere

[@_sabot]

Sounda pretty cool, unfortunately my Mac doesn't have F13 😢

[@diminishedreturn]

@@_sabot The Magic Keyboard with NumPad goes up to F19. X-Mas comes around sooner or later.

[@AnthonyMarchenko]

⇧⌘J - select the visible file in project navigation, was a real discovery for our team. Really help to navigation throw complicated architecture try it! Cheers

[@Nilely]

Thanks. All tips are usefull. Tiling the simulator is most useful tip for me from all the new tips I learn.

[@AlanW]

"Which is useful for the NEVER times you want to print out your source" 🤣

[@MartensFamilyHomeMovies]

My tip is to always check your explanation first when I want learn something new with Swift.

[@luyokai]

Never thought I knew so little about Xcode until I watched this video.

[@noamif]

i've learnt so much from this man it's not even funny anymore

[@AX100G]

The tip about adding init to classes is also useful for structs. the member wise init provided by the compiler is always “internal”. If you want a public one you can: Change your object from struct to class, use the Xcode refactoring tool to generate the init, change it back to a struct... and then make the generated init public.

My tip: the disabled breakpoints also leaves a blue line on the right scrollbar. Just click twice in front of your actually important lines and work with a quick visible reference on the scrollbar. You can remove them after work done, from the Breakpoint Navigator.

[@_sabot]

My tip for you guys is something some may know from the JetBrains IDEs. They have this little target icon above the file tree and if you press it, it will show you where the currently in the editor opened file is located in the file tree. This is very useful in large projects after you navigated in your editor by clicking on method names for example. I missed it so long in Xcode until I found out it has it too, but it's little bit more hidden. You have to right click in the editor, then -> Navigate -> Reveal in Project Navigator

[@ShinnyxAKAvincent]

Try CMD+Shift+J :)

[@magedmohamed4622]

Thank you for your helpful explanation

[@mrvfino]

Thanks! I always suggest your website and content to newer iOS developers that i meet. It's a go to resource. Succinct yet still very informative.

[@sergiobost4891]

My favorite was 'Generating an interface file' - Awesome

[@trendz4422]

How its useful? IDK how to use it.

[@sergiobost4891]

@@trendz4422 it’s only really useful when browsing through others code, it’s gives you a birds eye view of what’s going on. Otherwise you would have to figure out what each component does and individually

[@mirkaram548]

No. 5 was that I was don't know before, that's really helpful. But what for i was hoping was "DUPLICATE CURRENT LINE", its really handy shortcut when when needed declaration of same type and modifier variable.

[@MrShumylo]

Fantastic! So many useful tips. Cheers for this!

[@danielwatson6529]

Code snippets library is my fave, i save all sorts in there

[@Aotearoas09]

Thanks. Something to learn and remember for the weekend.

[@thephantom1237]

Thanks Paul. these will save a-lot of my time.

[@abirhasanzoha1291]

Thanks for the tips. I really liked the spell checker as I do typo a lot. 😬

[@yuriiohiria5559]

Awesome! Learned many new useful things! Thank you, Paul!

[@h3sperian]

Thanks for the tips, I learned 2-3 new life-savers ❤️ I like to move things, and so do I like to move code in my source file. Mostly when dragging around some piece of useful code ⌥ + CMD + [ -> move line up ⌥ + CMD+ ] -> move line down

[@gakkieNL]

Great tips, some new ones here! Thanks 🙏

[@fernandomontes5087]

That indent shortcut is going to save me a lot of time.

[@MartensFamilyHomeMovies]

too bad you didn't guess it was there.

[@elbot441]

Its good but got a bad thing when using with swiftlint, If you have an empty space (between two line for readability ) it will add space and create a warning for swift lint

[@PaulPeelen]

Even better, there is an option in Xcode which will automatically re-indent on paste. You can find it in File > Preferences > Text editing > Indentation > Check "Re-indent on paste"

[@volimpia]

Number 1 is lifesaver, thank you for this video. I will be using it and number 8. Some i didn't know about, some did. Can anyone recommend some videos about testing?

[@vladimirmoor]

BIG thanks for this huge amount of tips!

[@emilytomsUA]

Thank you for sharing, Paul!

[@mostafaelshazly6734]

[@chingshenchen]

Thank you for your share. It's really useful.

14:43 NumberedRow.init???? I guess this is Swift being really clever, but can you please show the expanded version that shows how the unnamed List value is passed to the NumberedRow view?

These were so, so great.

[@danuff]

Thanks for these tips!

[@sirkastic]

My favourite is the 'Quicken' feature to help speed up builds. If you are finding build projects slow (especially Unity builds for me) press CMD + Q whilst XCode is buiilding the project and it will allocate more system resources to that task

[@AngleIron426]

Excellent. Thank you.

[@onecarwood]

Very good tips!

[@williamsquires3070]

Okay, but how can I force Xcode’s code editor to ALWAYS insert 2 spaces (or however many I want in the preferences) whenever I hit the key? This is super aggravating when I want to tab over an opening ‘{‘ and nothing happens. 😫 Even better, is there some way to have it put the open curly brace on the next line after a “func” declaration, and indented one level?

[@prachibile2798]

Amazing tips

[@andreychirkov1904]

Does anybody know why Xcode puts generated initializer or protocol conformance methods BEFORE other declaration bun not AFTER. Maybe to train us to not forget cmd-x cmd-v? )))

[@YannSaintLaurent]

Do you have a debugging tips 101 video?

[@dodilodi1278]

for tip No1, I find it more easy not to use the Editor, you can simply do right click on the class name -> refactor > generate membervise initializer
