Because my iPad update to iOS 13 then my old app doesn't work correctly, but source code of my App is Swift 2.3 and my Mac also update to Mac OS Catalina, when I download Xcode 8.3 from Apple Developer web site and install it alert Xcode 8.3 is not from Apple so it can't open.

The Xcode IDE combined with the Swift programming language make developing apps easy and fun.Xcode includes the Xcode IDE, Swift and C/C++/Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features:Innovative tools help you create great apps• Swift is an intuitive programming language that is safe, fast, and modern• SwiftUI is a revolutionary framework to create user interfaces with a declarative Swift syntax• Playgrounds are a fun way to experiment and interact with Swift code• View debugging shows a 3D stack of all your app's UI view layers at runtime• Split editors in virtually unlimited ways, show previews, or choose an assistant to see related content• Live issues display errors as you type, and Fix-its improve your code with just a click• Source control navigator and service integrations help you manage code across a teamSwiftUI and Interface Builder make it easy to design your interface• SwiftUI uses declarative Swift code that clearly describes your interface• Design canvas graphically builds UI views using the library of controls and modifyers• Preview SwiftUI code or UIKit interfaces in different screen sizes, orientations, and font sizes• SwiftUI code is always in perfect sync with the graphical design canvas and previews• Animations are built using simple commands that describe the action you want to seeProfessional editor and debugger keep your code front and center• Refactoring makes it easy to modify the structure of Swift, Objective-C, C, and C++ code• Open Quickly instantly opens any file within your project• Data tips and Quick Look can inspect a variable by hovering your mouse over code while debuggingInstruments for performance analysis• Compare CPU, disk, memory, and GPU performance as graphical tracks over time• Identify performance bottlenecks, then dive deep into the code to uncover the cause• Analyze your app directly, or sample the entire system with very little overhead• Create custom instruments with unique visualizations to analyze your own code and frameworksTo test or run applications on an iPhone, iPad, Apple TV, or Apple Watch all you need is a free Apple ID. To submit your apps to the App Store you must be a member of the Apple Developer Program. Some features may require Internet access.

    Providing feedback and reporting bugs

    Xcode 8.3 Download

    Your feedback goes a long way toward making Xcode even better. With Feedback Assistant, you can report issues or request enhancements to APIs and tools. Provide detailed information about issues, including your system and developer tool versions, and any relevant crash logs or console messages. To ask questions and find answers from Apple engineers and other developers, visit the Apple Developer Forums.

    Invalid private key and certificate pairing

    Xcode 8.3 Download Free

    If you receive an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain,” the Keychain Access application on your Mac is missing either the public or private key for the certificate you’re using to sign your app.

    Xcode 8.3 Download

    This often happens when you're trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

    Download

    For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.

    Apple security updates

    For information on the security content of Xcode updates, visit the Apple security updates page.
