Unable to find a specification about promises HOT 11 CLOSED

I believe something is broken with your CocoaPods setup.
Wonder if the following could help:

pod repo remove master
pod setup
pod install

from promises.

As suggested by @shoumikhin following worked

pod repo remove master
pod setup
pod install

from promises.

Just tried pod install for the following Podfiles:

target 'SomeTarget' do
  pod 'PromisesObjC', '~> 1.2.3'
end

Along with modifications like:

target 'SomeTarget' do
  pod 'PromisesObjC'
end

and:

target 'SomeTarget' do
  use_frameworks!
  pod 'PromisesObjC'
end

Every time the pod was installed successful.

hmm which xcode version you are using? or this should not affected by that? I am using xcode 9.4

from promises.

Same Xcode version, it shouldn't matter.
Try pod install --verbose, maybe you'd spot something interesting.

here is the output

pod install --verbose
