RubyMotionを使ってみる。すでに、以下のcocoaというgemを使っているが、うまく動かないケースがあり、まずは他のプラットフォームも使ってみようという意図。

RubyMotionの登場は、2012年5月。

RubyMotionの後継として、DagonRubyが登場しており、RubyMotion自体はディスコンが決まっている。

こちらは、SDLの後継のようだ。Cocoaの機能を使いたいという意図で使うものでは無い。マルチプラットフォームのゲーム開発に使う。
ただ、RubyMotionのversion upは続けられており、version 7.6では、macOS Catalina（10.16.6）、Xcode 11.6、Swift 5への対応は行われている。

* [Xcode] Added support for Xcode 11.6.
* [Bugfix] `Pointer.new` top level retain behavior has been reverted. If you were having crashes
in RM 7.5, this should resolve that issue. The retain logic for Pointer has instead
been scoped down to the access of the value. If you want the Pointer to auto release, instead of:
```
@pointer = Pointer.new(:object)
someObjectiveCFunction(@pointer)
.... later in code ....
puts @pointer.value
```
You will need to do:
```
pointer = Pointer.new(:object)
someObjectiveCFunction(pointer)
@pointer_value = pointer.value_with_autorelease
.... later in code ....
puts @pointer_value
```
If the value within the Pointer is an array. Instead of:
```
@pointer = Pointer.new(:object)
someObjectiveCFunction(@pointer)
.... later in code ....
puts @pointer[0] # alias is @pointer.value_at(0)
puts @pointer[1] # alias is @pointer.value_at(1)
```
You will need to do
```
If the value within the Pointer is an array. Instead of:
```
pointer = Pointer.new(:object)
someObjectiveCFunction(@pointer)
@pointer_item_1 = pointer.value_at_with_autorelease(0)
@pointer_item_2 = pointer.value_at_with_autorelease(1)
.... later in code ....
puts @pointer_item_1
puts @pointer_item_2
```
* [Xcode Beta] Added support for Xcode 12.0 running on macOS Catalina. This is only
for Indie and Pro subscriptions. Big Sur plus Apple Silicon support will be released
at a future date. Come to the Slack channel for updates: http://slack.rubymotion.com.

ERROR! Deployment target 10.13 is not supported by this version of RubyMotion. If you are using the Starter Version, make sure you are running the latest version of XCode, and both `app.deployment_target` and `app.sdk_version` are commented out in the Rakefile. If you are updating to a new version of RubyMotion or Xcode, be sure to open Xcode at least once, run `sudo xcode-select --reset`, and then `rake clean:all default`.
