force_unwrapping rule catches IBOutlet Collections in swiftlint 0.9.1

[tapi]

IBOutlets are always force unwrapped and generally the force_unwrap rule ignores them.

However it appears as though with swiftlint 0.9.1 it is catching IBOutlet collections. ie.

@IBOutlet weak var constraint: NSLayoutConstraint!

is ignored by the linter but

@IBOutlet var constraints: [NSLayoutConstraint]!

is not ignored

I would think the IBOutelts should be caught by the force unwrap rule. They actually can be nil at times and cause a crash

They are not forced unwrapping, but are defining properties of implicitly unwrapped optional. Those two are not the same. So force_unwrapping rule is catching IUO would be the real issue.

Thanks for filing an issue.
This behavior has been changed by #537.
Maybe we need another approach for force_unwrapping.🤔

I opened PR #552 for fixing the issue #546, #547.
Feedback is welcome.
