Problem

You can't use bridging headers within a framework.

Solution 1 (umbrella header):

Xcode will automatically create umbrella header for you Cocoa Framework project. That will be the file named <FrameworkName>.h in the <FrameworkName> group/folder (where the rest of your sources are).

To include the required Obj-C header you need to set it as Public: select it in the project explorer (left pane) and change the property Target Membership (left—Inspectors—pane) from Project to Public.
Open umbrella header (<FrameworkName>.h) and import the required header as:

	import threading
	import asyncio

	async def run_coro_threadsafe(self, coro, other_loop, our_loop = None):
	"""Schedules coro in other_loop, awaits until coro has run and returns
	its result.
	"""
	loop = our_loop or asyncio.get_event_loop()

	# schedule coro safely in other_loop, get a concurrent.future back

	import asyncio
	import threading
	import random


	def thr(i):
	# we need to create a new loop for the thread, and set it as the 'default'
	# loop that will be returned by calls to asyncio.get_event_loop() from this
	# thread.
	loop = asyncio.new_event_loop()

	so A and B are structurally identical
	C reverses the order of the 8 and 32 bit Ints
	and D substitutes a string for the Int8
	then I try to read aaaa’s bits using B C and D overlays 😊
	C is printing the 8 bits of the A integer j and then the first 8 bits of integer k but somehow that still works out to one

	when I hit D it doesn’t find a string so prints a blank

	but the important point is: it doesn’t check anything, and doesn’t crash

	import Foundation
	import ObjectiveC.runtime

	let myString = "foobar" as NSString

	println(myString.description)

	let myBlock : @objc_block (AnyObject!) -> String = { (sself : AnyObject!) -> (String) in
	"✋"
	}

	func countLabelLines(label: UILabel) -> Int {
	// Call self.layoutIfNeeded() if your view uses auto layout
	let myText = label.text! as NSString

	let rect = CGSize(width: label.bounds.width, height: CGFloat.greatestFiniteMagnitude)
	let labelSize = myText.boundingRect(with: rect, options: .usesLineFragmentOrigin, attributes: [NSAttributedStringKey.font: label.font], context: nil)

	return Int(ceil(CGFloat(labelSize.height) / label.font.lineHeight))
	}

	var content = UNMutableNotificationContent()

	content.title = "Title"
	content.subtitle = "Subtitle"
	content.body = "Text"
	content.sound = nil
	content.categoryIdentifier = "categoryName"

	var personNameComponents = PersonNameComponents()
	personNameComponents.nickname = "Sender Name"

	#!/bin/bash
	#
	# git-mv-with-history -- move/rename file or folder, with history.
	#
	# Moving a file in git doesn't track history, so the purpose of this
	# utility is best explained from the kernel wiki:
	#
	# Git has a rename command git mv, but that is just for convenience.
	# The effect is indistinguishable from removing the file and adding another
	# with different name and the same content.
