Swift URL with Custom Scheme in Query String Fails

• Notice that some parameters are URL Encoded*

Code Block 
https://xxxxxx.auth.us-east-1.amazoncognito.com/logout?client_id=49jaf4a848hakh&logout_uri=myapp%3A%2F%2F&redirect_uri=myapp%3A%2F%2F&response_type=token

• I get a run time error using this URL in a data task that says:*

Code Block 
Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" 
UserInfo={NSUnderlyingError=0x60000202ccf0 
{Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}, 
NSErrorFailingURLStringKey=myapp://, NSErrorFailingURLKey=myapp://,
NSLocalizedDescription=unsupported URL}

• I already have "myapp" in my info.plist.*

Code Block 
	<array>
		<dict>
			<key>CFBundleTypeRole</key>
			<string>Editor</string>
			<key>CFBundleURLName</key>
			<string>com.***.yyy</string>
			<key>CFBundleURLSchemes</key>
			<array>
				<string>myapp</string>
			</array>
		</dict>
	</array>

• Below is the code to execute this simple URLSession data task*

Code Block 
				let s = URLSession.shared
				let u = URL(string: "https://***.yyy.auth.us-east-1.amazoncognito.com/logout?client_id=7c2aqa0fibv51v8valq6pagtoq&logout_uri=myapp%3A%2F%2F&redirect_uri=myapp%3A%2F%2F&response_type=token")!				
				
				let t = s.dataTask(with: u) { (d: Data?, r: URLResponse?, e:Error?) in
						if e != nil {
								print("error: \(e)")
						}
						let decoded = String(data: d!, encoding: .utf8)
						print("Data: \(decoded)")
						print("url Response: \(r)")
						print("Breakpoint")
				}.resume()

• I've tried with both URL strings below and still get the same error*

Code Block 
let u = URL(string: "https://***.yyy.auth.us-east-1.amazoncognito.com/logout?client_id=7c2aqa0fibv51v8valq6pagtoq&logout_uri=myapp%3A%2F%2F&redirect_uri=myapp%3A%2F%2F&response_type=token")!				
let u = URL(string: "https://***.yyy.auth.us-east-1.amazoncognito.com/logout?client_id=7c2aqa0fibv51v8valq6pagtoq&logout_uri=myapp://&redirect_uri=myapp://&response_type=token")!
