Which one would be the best for the next 3-4 years? Thank you!

Sometimes it comes back. SourceKitService is never-ending reading gigabytes from the disk. There is a so much disk use that Xcode and other application suffer and are sometimes stalled. I don't think killing it is a good idea but I hope to find a solution to avoid this penalty.

Less than 5 seconds after I swipe up from the bottom (with my app running the foreground, not from the app switcher) to send my app to the background on my iPad (running iOS 14 Beta 3) while running my app with the debugger attached through Xcode 12 beta 3, connected to my Mac with a band new lightning cable, I see this message (and then my app is no longer running) :- Message from debugger: Terminated due to signal 9 This happens consistently, without me trying to quit the app from the app switcher. Since this is a beta, I'm not sure if this is an issue in my app, an issue in Xcode 12 beta, or an issue in the iOS 14 beta.  Does anyone have any thoughts on what's going on?

Anybody know if it's possible to get Playgrounds (and, I'm guessing, Live Previews) to enable full trust got a root certificate, like we can do in the Simulator? My company's experimenting with a new security platform that involves installing a root certificate. So, any https requests we're making in that render in Xcode are failing. The root cert's already in Keychain and available for general use on Mac.

Hi everybody, I am a beginner developer and in my Shopping List application I faced a problem of a massive controller. I have read several articles on this topic. They helped me to understand some things, but they don't solve this problem completely. Therefore, I decided myself to try to organize the structure of the view controller in terms of the tasks to be solved. For example, my application has a table view controller (screen) for list of items. This TVC should perform the following main tasks: Show list of Items. Select items for Shopping. In turn, the first main task includes the following actions: Show data in a table Supporting Edit Actions - Add, Delete, and Change Data. Supporting Usability Action - Sort (reorder, rearrange) Data. The second main task includes the following actions: Mark Items with a Checkmarks In addition, this TVC should to save and load data. Common / General Supporting Tasks for Both Main Tasks: Save data to the archive file Load Data from the archive file When I implemented all the functions of the controller, I got the following real structure: Supporting Common / General Task: Load data Load data from database Load/Update data after changing in other View Controllers Main Task 1: Show data in a table. numberOfSections numberOfRowsInSection cellForRowAt Supporting Edit Task for Main Task 1: Add a new item. Calling a method from an Extension Supporting Edit Tasks for Main Task 1: Delete and Change actions leadingSwipeActions deleteAction changeAction Unwind Action - Return from Change Screen for Cancel button Supporting Usability Task for Main Task 1: Sort list of items. Show sort/reorder/rearrange button and its title Which rows can be reordered (Allow to reorder) Reorder items in list Remove Delete button from screen Main Task 2: Select items (mark them with checkmarks) didSelectRowAt Supporting Usability Task for Main Task 2: Clear all Checkmarks. Uncheck all items button Supporting Common / General Task: Persist Data (Save data to the archive file) Save/persist data before View will disappear  viewWillDisappear Could you tell me is this approach optimal? May I have some other problems later which I do not know about yet? Any ideas are appreciated.

I'm trying to inspect network traffic on an iphone 11 pro, I use: rvictl -s [UDID] on terminal and it closes after a couple seconds without any error. I know the UDID is correct because if I use a wrong one it brings up the help . I installed most of the extra tools I found for xcode and such and rvictl is available, it just doesnt work.

Hello, I have added a widget extension in my iOS app but when I run the iOS app, it doesn't appear in widget gallery. So I tried to run the widget extension directly and most of time I get this error : SendProcessControlEvent:toPid: encountered an error: Error Domain=com.apple.dt.deviceprocesscontrolservice Code=8 "Failed to show Widget 'com.Ce-dricLoneux.School-Companion.WidgetsSchoolCompanion' error: Error Domain=SBAvocadoDebuggingControllerErrorDomain Code=1 "Failed to get descriptors for extensionBundleID (com.Ce-dricLoneux.School-Companion.WidgetsSchoolCompanion)" UserInfo={NSLocalizedDescription=Failed to get descriptors for extensionBundleID (com.Ce-dricLoneux.School-Companion.WidgetsSchoolCompanion)}."

In the settings of the iOS apps, section : Framework, libraries and embedded content : The widget .appex is there so I don't understand why the widget extension isn't packed with iOS app.

I get the following compilation errors on XCode 12 that are not there when building the same project with XCode 11. preferredAutoMicrophoneLocation = AVAudioSession.Location.orientationFront Error: Type 'AVAudioSession.Location' has no member 'orientationFront' Has something changed in the new iOS SDK?

While trying to build our project with Xcode 12 I ran into multiple build failures while rebuilding our dependencies with Carthage. I always end up getting this linker error: Undefined symbols for architecture armv7: "type metadata for Swift.StringObject.Variant", referenced from: outlined init with take of Swift.StringObject.Variant in CountryCodePickerViewController.o ld: symbol(s) not found for architecture armv7 This happened for me for both Alamofire and PhonenumerKit; therefore, this looks like an issue with the new Xcode and not the frameworks themselves. Archiving them with Xcode 11 works without a problem. As an intermediate workaround I removed the armv7 architecture from the valid architectures.

Hello!I am using Delphi to create a cross-platform app.Android is absolutely fine, but iOS is giving me no end of grief.The main problem is that I can't run my app on an iPhone X either as an emulator (because Delphi currently lacks support for MacOSX 64-bit) or as a device. The latter should indeed work, but I am completely new to iOS development so chances are I'm being a knob.When trying to run on the device, the app doesn't even build properly because Delphi says that "File was built for x86_64 which is not the architecture being linked(arm64)". I have a strong suspicion that this message is coming from the Apple toolchain rather than Delphi. The file being referred to here is AudioToolbox.In order to try and work around this issue, I am trying to download and install the command line tools for previous versions. I can download them alright and open them but then nothing happens and I am wondering why. What I get is the opened box which suggests it's trying to unpack the thing but it sits there doing nothing. I don't think it requires admin privileges because then it'd query for my password, but it's not.What am I doing wrong? Can somebody please help me figure out my missteps?Thank you!
