Improve installation instructions

Hey! I'm having a little trouble integrating with beta 9 (upgrading from a much older version, so it may not be a beta 9 specific issue).

Currently, Carthage is telling me the PINRemoteImage wants these things:

*** Checking out libwebp at "v0.5.1"
*** Checking out PINOperation at "1.0.3"
*** Downloading PINCache.framework binary at "3.0.1 Beta 4"
*** Downloading PINRemoteImage.framework binary at "Beta 9: Support for resuming downloads, faster operation queue"
*** xcodebuild output can be found in /var/folders/dz/30qkdl_13rb525_f_d70g3mr0000gn/T/carthage-xcodebuild.RL1rde.log
*** Building scheme "PINOperation" in PINOperation.xcodeproj
*** Building scheme "iOS" in PINCache.xcodeproj
*** Building scheme "PINRemoteImage" in PINRemoteImage.xcodeproj

I've integrated all 3 frameworks into my target (added to linked libraries & carthage copy-frameworks), but I'm getting a runtime error on launch, saying

dyld: Symbol not found: _PINDiskCachePrefix
  Referenced from: /Users/asb/Library/Developer/CoreSimulator/Devices/77E331CB-1C32-45DF-A704-0F665702520E/data/Containers/Bundle/Application/8FD99541-2F2F-4C63-A5BE-BAC7071F2965/wrytr.app/Frameworks/PINRemoteImage.framework/PINRemoteImage

and I'm not sure where it's coming from. Also, do I need to do anything with libwebp, or is that handled for me? Any ideas why dyld cant find _PINDiskCachePrefix? I grepped and found the symbol PINCache, but I'm (almost completely) sure I've integrated PINCache correctly, so I'm not sure where the complaint is coming from.

libwebp is linked into PINRemoteImage automatically if you're using carthage.

I'm not sure why you're getting a runtime error, can you upload a sample project?

Yup! I'll try to repro today On Wed, May 24, 2017 at 10:26 AM Garrett Moon notifications@github.com wrote:

Hmm, so it seems like my Carthage setup is just super weird for the one project I'm working on. Anytime I run carthage update, it fails, but if I run carthage build --no-skip-current from inside pinterest/PINRemoteImage, and drag those binaries over to my project's Carthage/Build/iOS, it works for me.

The only difference is that when I build pinterest/PINRemoteImage I'm building the head, instead of 3.0.0-beta.9 in my project. I'll try with pinterest/PINRemoteImage master soon

Ok, I'm going to close this for now, but report back and I'll re-open if necessary.

I have this issue also: dyld: Symbol not found: _PINDiskCachePrefix

I have included PINCache, PINOperation and PINRemoteImage correctly as normal too, a fresh checkout of my app and running carthage update gives me that missing symbol error when trying to run the app.

[AndrewSB]

My fix was to clone PINRemoteImage and do a carthage build --no-skip.... Then drag the built stuff into my project

Good to see that this wasn't just a my-machine sort of problem, I feel as if there's some weirdness with the exact checkout versions being built On Thu, Jun 22, 2017 at 1:40 AM Robin Hayward notifications@github.com wrote:

Yea thanks very much for sharing, that did also work for me.
