Please provide support for iOS 8.0 about swiftyrsa HOT 3 CLOSED

@iba-nongkhlaw Thanks for opening an issue.

I'm a bit torn on this matter.

One one hand, changing the minimum version will most likely not break anything. I don't believe Apple has modified the keychain features significantly between 8.0 and 8.2 in a way that SwiftyRSA would work on 8.3 but not 8.0.

On another hand, Apple recommends setting the minimum SDK version to the latest subversion of the version that you support. For instance, if you support iOS 8 and iOS 9, you should set the minimum SDK to iOS 8.4. See http://asciiwwdc.com/2016/sessions/213

In fact, the general idea is that you take the current shipping version, so 9.3, and then set your deployment target to one version back, maybe 8.4.
But don't go to 8.3 or 8.2 anymore because then you and your customers don't benefit from the improvements that we've implemented under the hood in that 8.4 release.

In addition to that, we've never tested for 8.0, 8.1, and 8.2. We'd have to update our travis file to handle that, create a new release, handle support if errors come up, etc. All that to support the probably rare case of users not upgrading to the latest minor version of their OS.

So I'm leaning towards not supporting 8.0-8.2 just from a support perspective. If you absolutely want to integrate with SwiftyRSA, you still have a couple options:

• Copy-paste the files directly in your project
• Setup some kind of pre/post install hooks (cocoapods has some, carthage might too?) that modifies the minimum version to 8.0 after downloading the SwiftyRSA project.

Another option is to have you own the "feature" in the sense that you could modify the minimum SDK, add the appropriate CI test, and ensure support if anything goes wrong. I would be totally ok with that, let me know if you wanna join the team :)

My 2c; I think that the situation is slightly different for a framework than an app in the context of the Apple presentation. An app developer needs to make a decision as to which version of iOS they will support; this could be based on features, their customer's devices etc. If a framework mandates a newer version then it is, to a degree, taking that decision for them. Of course they can modify the framework themselves or even choose not to use the framework; it is free after all.

Also, since Apple doesn't exclude devices on subversions of iOS, there isn't a device that can run 8.0 and that can't run 8.3.

The fact that testing may be difficult, 8.0 is really old (we are about to see iOS 10), there is no reason that people on 8.x shouldn't be on at least 8.3 and this project uses security features leads me to think that we should not change the minimum level

I agree with @paulw11, especially on his last point about security features/fixes between 8.0 and 8.3. Closing this issue. @iba-nongkhlaw You still can patch SwiftyRSA's sources in your project, though we won't officially support it.
