Overview

I'm still learning how to code and would love to get recommendations on how to learn swift/swiftui for iOS/macOS app development. Any recommendations are welcome :)

Running a project from Xcode 12 seems to be very slow during launch. Even the example projects from Apple. Basically it feels as if the app is stuck on the launch screen? However, if I unplug from my Mac and just launch via tapping on the App icon, it's super fast. Anyone is having the same issue?

I have upgrade Xcode to last release on 15 december 2020. Now it freezes every minutes for 5 minutes it's unusable. Are there some solutions?

I've updated to Big Sur from Catalina and I'm having trouble when connecting to WiFi networks. At first no network appeared and now even though it has connected silently to my usual network, it is showing as no connected, but internet actually works. Anyone having this kind of problems so far? I haven't seen anything related on the forums nor the release notes.

After I updated Xcode 12 to Xcode 12.0.1 I can't download simulators anymore. Under Preferences->Components, the list of Simulators is blank. How can I still add an iOS 13 simulator?

Hi all Anybody knows why I'm getting a weird yellow color in the navigation bar and the tool bar?. Simulator with iOS 14.1 it looks good, but iOS 14.3 looks with the yellow color. I disabled all the option in the Debug menu -> Color options... Thanks!

Really I’m gonna Die if you not fix it ASAP ios 13.7 was best when I updated to iOS 14 then everything Gone to Hell pubg lags in game between matches only iOS 14 and iOS 14.1 users facing PUBG lag render issue fix it or I will never update your shit updates in my life in-between matches it start frame drops and we die like a noob because of this so bring new update and iOS 14.2 must fix it 😡

I'm trying to do a simple application in SwiftUI taking advantage of SwiftUI 2.0's new multiplatform project template, and I wish to add the option to collapse the sidebar as many other apps do. I've got an extremely simple sidebar I did following the Fruta example project, and I tried adding a boolean state variable that controls whether the sidebar should show or not, but that doesn't work because when the sidebar is hidden, the main view is turned translucent. On iPadOS, a button appears on top of the sidebar that allows to collapse it. How would I do this in macOS? Is there a way to natively achieve this in SwiftUI, or I'll need to resort to a UIKit workaround?  Please note I'm using macOS Big Sur, Xcode 12, and SwiftUI 2.0 Thanks in advance.

Hi. I am pairing my Apple Watch Series 5 to my iPhone running ios 14. The pairing is successful but unable to proceed with the set up because an update is needed to be downloaded first. I updated the os for watch but I keep on getting “Unable to Check for Update - Checking for a software update failed because you are not connected to the internet”. I am definitely connected to the internet. Watch was reset to factory defaults and I am now pairing it as a new device but it fails due to the issue mentioned above.

My app ran without any crashes while using Xcode 11.1. After updating to XCode 11.2, my app experienced a crash:*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _UITextLayoutView because no class named _UITextLayoutView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'This crash seems to occur during a perpare for seque, before any of my views appear on the screen.Any idea on the cause or solution?Thanks.

Hi, we submitted an iPhone app for TestFlight review last week so that we could distribute to our beta test group. It was rejected over the weekend but we have not received any rejection emails containing details or for that matter can't find any reason online? Have raised a question online to the iTunes review team and awaiting response but wondering if any other developers have had similar issues recently with not receiving communications from the review team? I am obviously checking SPAM folders and received OK the state change email when the app was first uploaded but nothing since? Thanks in advance Graeme

SwiftUI previews don't seem to work in Xcode 12, beta 5, when using Firebase Analytics. The app builds and runs fine to simulator or device, but fails generating SwiftUI preview for a widget with the following message: ld: in /Users/../.../Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector(FIRAnalyticsConnector_e321ed8e3db06efc9803f6c008e67a34.o), building for iOS Simulator, but linking in object file built for iOS, file '/Users/.../.../Pods/FirebaseAnalytics/Frameworks/FIRAnalyticsConnector.framework/FIRAnalyticsConnector' for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) It was working fine in beta 4. Anyone else seen this? Any ideas?
