Before running the open command I ran the following and I was able to use Xcode 13.2.1 in Venura. sudo xcode-select -s /Users/username/Downloads/Xcode.app

I have tried the most common suggestion of running it from command line but no luck. Command: open /Users/username/Downloads/Xcode.app/Contents/MacOS/Xcode Error: Xcode[3762:21719] [MT] IDEPackageInstallerHelper: Generic message for error: Error Domain=PKInstallErrorDomain Code=201 "An error occurred establishing a connection to the installation service." UserInfo={NSLocalizedDescription=An error occurred establishing a connection to the installation service.} I'm unable to download and install command line tools separately. It complains about the macOS version. I share the same sentiment as @zumacinsmity. On a regular day I support versions of the apps that are developed using older versions of Xcode. At least one major version older. In my case I was trying to install Xcode 13.2.1

@awsw please see https://developer.apple.com/library/archive/technotes/tn2339/_index.html#//apple_ref/doc/uid/DTS40014588-CH1-WHAT_KEYS_CAN_I_PASS_TO_THE_EXPORTOPTIONSPLIST_FLAG_. You need to create the plist manually.

I still see the problem in XCode 13.2.1. However, this only happens if I use the command line. Randomly fails with this error in pods. xcodebuild archive

Earlier I mentioned that @beruta's solution worked for me but it started failing again. What worked for me is cleaning Xcode project build files. "About This Mac" -> Storage -> Manage -> Developer This is also a neat way to clear up some space when you are running out.

Your app will not be removed. However, functionality is not guaranteed for deprecated APIs.

You can get the Javascript to work by adding the WKWebView to the view hierarchy. You can hide the web view by giving it a zero rect. let config = WKWebViewConfiguration() _webView = WKWebView.init(frame: CGRect.zero, configuration: config) instanceOfYourView.addSubview(_webView!)

Assuming the website you are loading uses User-Agent to change content/layout/presentation the following will work. let config = WKWebViewConfiguration() if #available(iOS 13.0, *) { /** In iOS 13 and above WKWebViews in iPad has the ability to render desktop versions of web pages. One of the properties they change to support this is the User-Agent. Therefore forcing the WKWebView to load the mobile version. */ let pref = WKWebpagePreferences.init() pref.preferredContentMode = .mobile config.defaultWebpagePreferences = pref } _webView = WKWebView.init(frame: CGRect.zero, configuration: config)
