Sorry about that. I forgot to add "pidiOS64" to the [ComponentPlatformsAttribute], so the problem was actually that the Delphi IDE didn't KNOW the components were compatible with iOS64, even though everything would have compiled and worked
Anyway ... Thank you for reposting this.
The update to fix this IDE problem is now ready for download (RTC SDK v6.54).
Best Regards,
