I have the this issue when I run the app on iOS Simulator after updating to app to make it compatible with Xcode-16 and iOS-18. after upgradation to Xcode-16 its giving the above error "Executable path is a directory" .This app work fine on Xcode-15 . Note - The issue with iOS Simulator only. From XCode-16 build is created successfully and installed in iOS device.

I have a valid dev certificate and created a valid provisioning Profile. I have added the Device UDID too , which I can see in provisioning Profile too. In XCode-16 both certificate and provisioning Profile looks good and no issue here with the expiration date too. Issue - While running the app on my iPhone connected to Mac.its shows the build is successful but shows the followinf errors . An IPA of APP failing the installation. Unable to install the App `A valid provisioning profile for this executable was not found. Domain: com.apple.dt.MobileDeviceErrorDomain`
