Xian - you can use Diawi, HockeyApp, Crashlytics, or TestFlight / iTunes Connect:
Send us your beta file quickly via Diawi. After uploading your file, Diawi creates a unique short URL to access the installation page (for ex: aBcDeF). When opened in Safari on the iOS device, the page will display a link to install the application. Add the testing link to your submission form under “iOS Build Link”.
Please note that you will need to include provisioning for one or more of the UDIDs below.
Please note that HockeyApp allows you to send test builds quickly, but there is a fee to use this service.
# Beta by Crashalytics
Send us a beta test via Crashalytics. Use our testing email (email@example.com) and UDIDs to provision a build and send us a link via the “Share Links” button. Make sure to also add the testing link to your submission form under “iOS Build Link”.
Pro tip: Make sure you add the UDIDs to your build to speed up the process. There’s no review, but all builds still need to be received in full before the submission deadline.
Share a build with us using our email address, firstname.lastname@example.org. Please note that if you add us as an “External Tester,” your app will need to go through Beta App Review before you can send the build. Builds must be received by the submission deadline to be eligible - so plan for extra time!
