### Changes:
- `InternalAPI` is now `Sendable` to deal with new compilation error
- `PaywallEventStoreType` is now `Sendable`
- Extracted `SK2BeginRefundRequestHelperType` to make
`SK2BeginRefundRequestHelper` `Sendable`
- Updated `MockSK2BeginRefundRequestHelper` to be thread-safe and
`Sendable`
- Fixed compilation error in `DebugContentViews`
- Fixed compilation error in `DebugViewModel`
- Fixed compilation error in `StoreMessagesHelper`
### Context:
`#if os(iOS)` no longer evaluates to `true` when compiling for
`visionOS`
Which means we need `|| os(xrOS)`.
But to support older Xcode we need `#if swift(>=5.9) && os(xrOS)`.
But, fun fact, short-circuiting doesn’t work in `Xcode 13`.
And we still need that to run iOS <15 tests (`FB12223404` /
`FB12805891`)
💩
This works around that by defining our own `VISION_OS` flag.
### Changes:
- Added `VISION_OS` compile time flag to determine SDK
- Replaced `#if os(xrOS)` with `#if VISION_OS`
- Added flag to `Package.swift` (thanks @neonichu for helping with this)
Fixes SDK-3084
## Changes:
- Added new `ENABLE_CUSTOM_ENTITLEMENT_COMPUTATION` compile time flag
- Hidden `configureInCustomEntitlementsModeWithApiKey` behind
`ENABLE_CUSTOM_ENTITLEMENT_COMPUTATION`
- Added new `RevenueCat_CustomEntitlementComputation` SPM target and
library
- Added CircleCI job for `swift build --target
RevenueCat_CustomEntitlementComputation`
- Added new `SPMCustomEntitlementComputationInstallation` using the new
`configureInCustomEntitlementsComputationMode`
- Added CircleCI job for `SPMCustomEntitlementComputationInstallation`
- Added `FrameworkDisambiguation.swift` to avoid using `RevenueCat.`
disambiguation for files that
- Changed API testers to only use the new methods if
`ENABLE_CUSTOM_ENTITLEMENT_COMPUTATION` is defined
- Updated `DangerousSettings` to not expose
`customEntitlementComputation` publicly. The only way to use that now
with `public` API is through
`Purchases.configureInCustomEntitlementsModeWithApiKey`
- Updated sample app to use new library
