In iOS9, Apple added new feature called App Transport Security(ATS).

ATS enforces best practices during network calls, including the use of HTTPS.

Apple Pre-release documentation:

ATS prevents accidental disclosure, provides secure default behavior, and is easy to adopt. You should adopt ATS as soon as possible, regardless of whether you’re creating a new app or updating an existing one.

If you’re developing a new app, you should use HTTPS exclusively. If you have an existing app, you should use HTTPS as much as you can right now, and create a plan for migrating the rest of your app as soon as possible.

Add Below key in your info.plist & then see.

NSAppTransportSecurity

    NSAllowsArbitraryLoads
    

Even you can add specific exception,

NSAppTransportSecurity

    NSExceptionDomains
    
        testdomain.com
        
            NSIncludesSubdomains
            
            NSExceptionAllowInsecureHTTPSLoads
            
            NSExceptionRequiresForwardSecrecy
            
            NSExceptionMinimumTLSVersion
            TLSv1.2
            NSThirdPartyExceptionAllowInsecureHTTPSLoads
            
            NSThirdPartyExceptionRequiresForwardSecrecy
            
            NSThirdPartyExceptionMinimumTLSVersion
            TLSv1.2
            NSRequiresCertificateTransparency
