I’m currently developing an iOS application and I’ve encountered an issue with Xcode. Whenever I try to modify the Bundle Identifier of my application, Xcode crashes. The crash happens specifically when I click on the “Signing” option after changing the Bundle Identifier. Here’s the error message I get: “The app identifier ‘com.BikeTest.BikeRoute’ cannot be registered to your development team because it is not available. Change your bundle identifier to a unique string to try again.” Then I changed ‘com.BikeTest.BikeRoute’ to 'com.wuwuma.BikePowerRoute',and xcode crashed. I don’t have a paid Apple Developer account, and I’m wondering if this could be causing the issue. However, I believe I should still be able to modify the Bundle Identifier without Xcode crashing. I’ve tried restarting Xcode and my computer, but the issue persists. I’m using Xcode version 15.2 on macOS 14.3.1. Any help or suggestions would be greatly appreciated. Thank you!
